[bug\_fix] found packages and in

Change the \`package\` declaration in one of the files to match the other, or move one of the files to a different directory. The root cause is that Go strictly requires all .go files in the same directory to belong to the same package, but two files have conflicting package statements.

Journey Context:
A developer refactors a large \`main.go\` file by extracting helper functions into a new \`helpers.go\` file in the same directory. They run \`go build\` and get an error about finding both \`main\` and \`helpers\` packages. They initially think Go allows multiple packages in one directory if they are imported differently, similar to Java or Python. They check the Go spec and realize that all .go files in a single directory must share the exact same package name. They open \`helpers.go\` and change \`package helpers\` to \`package main\`. The build succeeds because the compiler now sees a single cohesive package in the directory, resolving the ambiguity.
